I am getting too much from unemployment to receive Medicaid, how can I get health insurance?

None of it's cheap, but you can see if your state has a pool for people with pre-existing health conditions who have lost their insurance. Many states do. You have a year to go before you can qualify for Medicare (unfortunately very common after so many layoffs of older workers). It's a troubling gap for folks of that age. Please contact your state insurance office for suggestions.
Good luck.
